ON OFF
DIGITAL SLOW SHUTTER (DSS)
Digital slow shutter slows the picture frame rate and increases the camera sensitivity under low
light conditions. Depending on the number of fields of integration the picture will develop a
granular appearance and motion may show some lag, resulting in a stereoscopic effect or streaking
on fast moving objects. These effects increase as the number of fields of integration increase.
Available settings include the following:
30 fields of integration maximum (default setting) – 1/2-second scene update rate.
16 fields of integration maximum – 1/4-second scene update rate.
4 fields of integration maximum – 1/15-second scene update rate.
OFF – Disables the DSS mode.
Digital slow shutter automatically adjusts the number of fields of integration depending on the light
level of the viewed scene, up to the maximum determined by the switch settings.
AGC (AUTOMATIC GAIN CONTROL)
AGC automatically adjusts the image to compensate for changes in light levels.
ON (Default setting) - Enables the AGC mode.
OFF - Disables the AGC mode.
BLC (BACK LIGHT COMPENSATION)
The BLC (backlight compensation) feature compensates for backlit scenes by enhancing objects in
the center of the scene.
OFF (Default setting) - Disables the BLC mode.
ON - Enables the BLC mode. Use this setting if a bright backlight is present and the subject in the
center of the picture appears dark or as a silhouette.
